Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars [PDF]
, 2009 We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which ...
